Question

Which of the following laboratory values may be used to assess the renal function of a patient prior to the IV administration of iodinated contrast media?

1. Blood urea nitrogen (BUN)
2. Creatinine
3. Glomerular filtration rate (GFR)
A. 1 only
B. 3 only
C. 1 and 2 only
D. 1, 2, and 3

Answer 1

The laboratory values used to assess renal function before the administration of iodinated contrast media are Blood Urea Nitrogen (BUN), Creatinine and Glomerular Filtration Rate (GFR), so the answer is D. 1, 2, and 3.

Step-by-step explanation:

Which of the following laboratory values may be used to assess the renal function of a patient prior to the IV administration of iodinated contrast media The correct answer is D. 1, 2, and 3. To assess renal function, medical professionals rely on three key values: Blood Urea Nitrogen (BUN), Creatinine, and Glomerular Filtration Rate (GFR). BUN is an indicator of kidney function that estimates the urea level in the blood.

Creatinine is a metabolite of muscle metabolism that provides a good estimation of GFR because it is filtered by the kidneys and only slightly secreted. GFR itself is a critical measurement of the kidneys' excretory function and is often estimated by creatinine levels in the clinical setting due to the impracticality of measuring inulin clearance.
